I have this whole plan which was to add bits and pieces of the lore behind SCP-3863 like once a week, but nobody understood that (it mentions it in the file) so they just insta-downvoted. I don't want to have EVERYTHING at the start, but I guess I have to. Any criticism you can give me? Because I REALLY need it apparently.

Right now I'm planning on uploading the basic document after recovery. I will be toning down the room immensely, and every other question will be explained [Object Class / Material Choice] over time (I plan on adding bits and pieces over a few weeks like they're discovering more).

govt, the feedback you have provided is vague and unhelpful. What did you like about it? What's cool about it? What minor issues do you have with the draft? You can potentially hurt an author more than help them by posting such minimal feedback. Staff prioritizes threads with fewer posts, so by posting this you are reducing the chances of the author receiving proper crit.

This complaint's gonna be hella subjective, but I'll say it anyway: this part if the sentence was implied, and therefore didn't need to actually be stated.

due to unknown reasons.

Ditto.

appears to

Unless it does not actually do something, I would strongly hesitate to use "appears to". This problem pops up several times in your draft, so I'll note it here for posterity.

Also, point of order: you've started 4 sentences in a row with "SCP-3863". That doesn't quite read well, unfortunately.

Due to this ability it has also proven difficult to injure SCP-3863, as most material phases right through their body. SCP-3863 can still be injured, however the only known way is by the object being coated in liquid uranium, liquid plutonium, or if the object is made out of Iridium.

would better be worded "As such, SCP-3863 is immune to conventional weaponry outside of such material make.", in my honest opinion.

Iridium

I only noticed this now, but you have a problem with inexplicably capitalizing material names.

SCP-3863 was discovered when there were reports of a ghost-like figure around the town of Oakland, California, where an explosion happened nearby.

can better be worded as "SCP-3863 was discovered in Oakland, California following investigations of spectral figures following an explosion.", in my honest opinion.

Your description should begin with what an object is, in the sense that you begin with a noun. So far, you've only offered me adjectives for the skip in question.

wearing a dog tag that says “Project: H.U.N.T.E.R”

No offense, but this is straight out of a bad b-movie, and I therefore find it incredibly hard to take seriously. I'd recommend ditching this part, since it adds extremely little in comparison to what it takes away.

with the back of the blade seemingly shaped to fit a human spine.

This is an annoyingly inscrutable phrase. What is it supposed to mean?

Attempts to remove SCP-3863's axe have been unsuccessful (Due to [REDACTED]).

I'd ditch the "(Due to [REDACTED])" entirely, it really adds nothing to the skip.

If a containment breach occurs, recapturing SCP-3863 is immediate priority due to SCP-3863’s hostility. If confronted by SCP-3863, all armed personnel are to surround and incapacitate SCP-3863 so they can be placed in a mobile, humanoid containment unit composed of Iridium to be moved to a temporary radioactive containment.

What you have here is a generic Guy What Is Very Dangerous without much flavor to flesh it out. Hell, even the main anomaly (selective incorporeality) is basically what 106 did better and more interestingly. While it's obvious there's some sort of story hook present, the rabbit hole is never explored, leaving little more than a hint to some larger story.

I realize, of course, that you intend to add more to it as you go, and to that I say: every mainlister should be ready to be judged upon the content that's presently there, rather than on the promise of more to come. If you cannot impress me with your article as is, I will almost certainly not be coming back for more.

I would just like to take a moment of your time to thank you for actually giving proper crits instead of the other two. Everyone I asked usually just said it was good and never what I should change, but after reading yours I see a lot of the stuff that's screwed up. With my next attempt at publishing I'm most likely going to have the first (out of three) pieces of the 'Project Files'. I will be taking 90% of what you wrote into consideration tomorrow and whip out an update by the end of the day. Thank you :)
